1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Patients with Class II Division 2 malocclusion, often presenting with severe deep overbite and poor facial esthetics, are one of the most challenging cases in orthodontic practice. This case report shows the successful treatment of a Class II Division 2 deep bite patient with multiple anterior crowns using clear aligners. After the extraction of Tooth 45, we moved the right mandibular molars mesially to achieve a Class I relationship. Cantilever arms and elastics were used to correct the molar mesial tipping. We precisely controlled the space between prostheses by digital design. At the end of the treatment, new porcelain crowns and the counterclockwise mandibular rotation improved the dental and facial esthetics.
